' Application filed August 7, 1922. Serial in. 580,055;

To all whom it may concern:

Be it known that I,-WI1.LIAM L. TAYLOR, a citizen of the United States,and a resident of Cincinnati, in the county of Hamilton "and State ofOhio, have invented certain new and useful Improvements in Tobacco Bags,of which the following is a full, clear, and exact description,reference being bad to the accompanying drawings forming part of thisspecification.

My invention relates 150' bags, such asare used for .tobacco, although,of course, the bags could be used forany desired purpose.

Inthe production of a one-pieceba for tobacco, it. is customarytoprovide a single blank having one half wider than the other. to provideflanges or tabs which can be fold ed in over the blank. To these tabscement is applied and the narrow end of the blank laid down over thetabs, so as to become.

cemented thereto and thereby forming a onepiece bagopen at one end.

Ithas been found desirable by me to form bags for articles which mustresist climatic conditions of moisture, penetrating odors and the liketo make them from paper which is of plural asphalt.

The asphalt makes a perfectly insulated.

The difiiculty informing a perfect bag of this substance lies in thefactthat itsadhesiveness is not perfect, and that incold weather itbecomes hard, and in hot weather, soft to a certain degree. Thus anyasphalt pasted paper is likely. to separate under strain, so as topermit the webs to part, and if this should occur in a bag, it wouldmake it useless for the purpose of'a container of semi-permanent nature.

It is evident that there is exposed to strain in the single bag which-Ihave briefly described above, the edges of the narrow ends, and thatportion of the tabs to which the narrow end is cemented.- The edges ofthe narrow end are exposed and are subject to peeling back to expose theasphalt layer, and the tabs are likely to separate from the op-.

posite wall to which they are glued and permit the bag to come topieces.

It is my object to so form the bag of my invention that neither of thesedangers are likely to occur, and in which the asphalt filler is notlikely to show at any exposed for ..a single bag.

ply and pastedtogether with I gether.

edges of the paper, and thus to smudge over onto the face of the bag,making it unsightly.

These objects and other advantages to be noted I accomplish by thatcertain construction and arrangement of parts 'to' be hereinafter morespecifically pointed out and claimed. 1

In the drawings, 1 Figure 1 is a plan view of the bag blank Figure 2 isa section on the line 22 thereof, enlarged so as to show the natureofthe interposed layers. Figure3 is a perspective view of the completedbag.

Referring to the shape of blank for a single tobacco bag having the ends1 and 2, with the tabs 3 located at the sides of the end 1. In formingup the bag, the end 2 is folded toward the end 1 across the center ofthe blank, with the tabs folded inside between the two fends of theblank. Cement is applied to the tabs orthe edges of the end 2, so thatthe tabs, and the end 2 are secured together, thereby forming asinglewall bag.

The paper Lemploy is formed of plies A and B, beween which is a binding'layer of asphalt 4. This asphalt is of a tacky and resilient andodorless and tasteless quality and binds the webs of paper to- Insteadof paper I might employ fabric or foil, although this willnot ordinarilybe called for in bags of this character which are made by machinery ingreat quantities, and used .for scrap tobacco, cigar pouches, and thelike.

blank, I employ the usual I tudinally of the sheet as indicated by theareas within the dotted lines 6 in Figure 1 v and as shown in theunshaded portions 6 in Figure 2. When the web is cut into blanks, thesebands are dis osed' along the edges of the narrow ends 0 the blanks andextend through the wide ends of the blanks. Other bands of suitablecementitious material are disposed along the edges of the tabs 3 asindicated by the areas included between the outer edges of the tabs 3and the dotted lines indicated at 5 in Figure 1, and as shown by theunshaded portions 5 in Figure 2;

If cement of different color than the asphalt were to be used for theareas the-ap arance of the outer sides of the bag mig t be marred withstreaks so that in order to avoid this l have found it preferable to mixa small amount of black material with the cement to' give the body ofthe paper in the bag the same appearance throughout. A suitable cementfor the areas indicated at 6 maybe provided by mixing casein or varnishwith asphalt, and a similar material may be used for the areas indicatedat 5.

Thus I show the narrow bands of casein or varnish 6, which may beapplied together with enough asphalt to give a black color, or which maybe so applied that the asphalt can become transfused into the casein orvarnish sufiiciently to change its color, but not sufiiciently to changeits strongly adhesive nature.

I have not limited myself to the use of particular cementitious materialfor the tab portions. Gasein. and varnish have waterproofing qualitiesand could be used instead of asphalt, except for their high cost. Alsothey could be used in a wide band, so as to take in the tabs and narrowend edges also, except for its high cost.

A good varnish mixed with a portion of asphalt tr colored black, orfilled in some other, way to giveit color and bulk, can be used incmaller quantities than the cement. Thus the narrow streams sufiicientto make permanent the edges of the narrow ends of the tab edgescemented. wherethey are protected by the overlap of the narrow end ofthe blank, and a narrow stream of'casein or varnishrunning along theblank so as to safely cement. together the edges of the narrow blank"where exposed, gives me a thoroughly insulated bag, and a bag whichisclean throughout and formed of a. single piece capable of being-madeup automaticall and very rapidly in s ecial machines ma e for thepurpose. Suc machines are -'now in use and have been for many years.

The characteristics of varnish or casein,

which are vegetable and animal gums .re-

nezis aee spectively and which makethem applicable to my purpose is thatthey are gummy substances and that they have insulating qualities. Ifwish to include in the term varnish or casein such gummy, insulatingsubstances as may be applied to a web of paper, fabric or foil, togetherwith some asphalt or in the absence of any asphalt alon the lines of thegum stream, and which Wlll serve as an adhesive of permanent naturebetter than asphalt.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

l. A bag formed of a blank of foldable material, said blank having oneend folded over, inturned tabs on the other end, and said firstmentioned end cemented to said tabs, said blank having a plural plynature between which plies is a binding, interposed layer of asphalt orlike substance, with certain portions of the blank having interposedstreams of varnish, casein, or the like at the exposed lateral edges ofthe completed bag, and saidblank having a nonasphaltic cement at theedges of the inturned tabs.

2. A blank for bags comprising a single member having a wide end and anarrow end, the extending portions of the wide end to serve as inturnedtabs, said blank being formed of two plies, at least, of paper,

fabric or foil, and the plies united by a binding interposed layer ofasphalt or like substance, with a narrow stream of varnish, casein orthe like extending between the plies lengthwise of the blank, so as tolie at the edges of the narrow end thereof, and with the as halt absentfrom lines extending lengthwlse along the tab portions of the blank andin its place a permanent binding interposed band of suitable cement.

3. A blank for folding lengthwise to form a bag comprising a wide endand a narrow end with extended portions of the wide end adapted to befolded to form sealing tabs and the blank formed of plies united by abinding interposed layer of asphalt or the like, with a narrow stream ofvarnish, casein or the like disposed between the plies extendinglengthwise of the blank along outer edges of the narrow end of the blankand extending through the wide end of the blank and means for securingthe tabs and the narrow end of the blank together, to form a bag.
